An interesting demonstration of a technique that can (usually) weed out the cheaters from those that aren't using cheats in a given solo scenario. It doesn't always work, but it should work enough of the time that you (as a scenario maker) will get much less mail complaining about problems from people who only encounter those problems because they've cheated to a place they shouldn't be. (It was inspired by, to some degree, Jason Harper's Level Detector, and can be similarly used to control where a player goes based on his playing style.) Like others in this genre, most of the information will be found in terminals within the demo map.
